Inclusion criteria

Inclusion criteria: 1. histologically proven oligometastatic colorectal cancer (Oligometastatic disease status defined as involving up to 3 organ systems; up to 3 metastases per organ system) 2. Any treatment line irrespective of previous chemotherapy lines 3.Patient treatment recommendation confirmed by an institutional multidisciplinary tumor board (MDT) 4.Metastases amenable to complete ablation/resection using different techniques (radiofrequency ablation, thermoablation, photon beam radiation, surgery, including minimal invasive resections) 5.Age >18 Jahre 6.Life expectancy > 12 months 7. signed and dated consent form

Exclusion criteria

Exclusion criteria: 1. Patients with metastases involving more than 3 organ systems (e.g. liver, lung, bone and retroperitoneal compartment) 2. Patients with peritoneal or pleural metastases 3. Patient having undergone Whipple Operation 4. Second carcinoma, except carcinoma in situ of the cervix or basal cell carcinoma. 5. Pregnancy

Design outcomes

Primary

MeasureTime frame
There is a proportionality between the fall of the free-circulating tumor DNA 8 weeks after therapy and 16-72 week interval and the progression free survival and / or overall survival. (Check of the degree of response)

Secondary

MeasureTime frame
Is tumor recurrence (Progression free survival) associated with a different profile of genetic alterations?
